A54SX32A-1TQG100M

Overview

The A54SX32A-1TQG100M is a Microchip SX-A series Field Programmable Gate Array featuring 48,000 system gates and 81 user I/Os. It operates within a supply voltage range of 2.25 V to 2.75 V at a nominal 2.5 V. The device supports a maximum operating frequency of 278 MHz and functions across a temperature range of -55°C to +125°C. Packaged in a TQFP-100 format, it utilizes antifuse technology for nonvolatile configuration.

Feature Summary

• Supports mixed-voltage operation with configurable I/O standards including 3.3V/5V PCI, 5V TTL, and 3.3V LVTTL.
• Features hot-swap compliant I/Os allowing safe insertion into active systems without power sequencing requirements.
• Includes boundary-scan testing capabilities compliant with IEEE Standard 1149.1 (JTAG) for diagnostic verification.

Applications

• High-performance logic integration requiring deterministic timing
• Systems requiring hot-swappable interface capabilities
• Secure designs utilizing antifuse nonvolatile architecture

Procurement Notes

Verify the specific suffix 'M' against official documentation to confirm military temperature grade compliance (-55°C to +125°C). Ensure the package type matches the required TQFP-100 footprint. Confirm RoHS status if environmental compliance is mandatory for the target assembly process.

Selection Notes

Select this component when 48,000 system gates are sufficient for the design complexity. Verify that the TQFP-100 package fits the PCB constraints. Ensure the design requires the extended military temperature range specified by the 'M' suffix rather than commercial or industrial grades.

Part Context

This part belongs to the Actel SX-A family of FPGAs, which utilize metal-to-metal programmable antifuse interconnect elements. The family provides high-speed performance with low capacitance routing resources, enabling fast signal propagation through DirectConnect and FastConnect architectures.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult manufacturer documentation for cross-reference information regarding discontinued speed grades or alternative packages within the SX-A family.
